Abstract

This survey aims to describe the mathematical literacy of state junior high school students in Kupang city, East Nusa Tenggara province. It was done not only due to the low achievement of Indonesian 15-year-old students in PISA but also because there are no surveys which had been done before to map the mathematical literacy of students in Kupang city. A total of 377 respondents who were the ninth grade students representing six state junior high schools in Kupang were collected by two-stage cluster randomized sampling. The students were assessed using fifteen problems adopted from PISA 2012 and some development researches with a product of mathematical literacy problems so that those items were highly reliable to measure students mathematical literacy. The categorization of students mathematical literacy was carried out using Mamdani?s Fuzzy Inference method. The input of fuzzification was a score of three process domains assessed by those fifteen problems, specifically formulating, employing, and interpreting. The output of defuzzification was students mathematical literacy score used to determine the category of students mathematical literacy. The results showed that the mathematical literacy of state junior high school students in Kupang city was generally classified as a low category.

Abstract

The environment can become a source of learning in a process of mathematical learning related to the real world. One source learning in the environment is cultural. Mathematical lessons that studied educated participants at school are sometimes different to important transatic problems that encountered in everyday life, makes it more difficult learning participants linking the links of furatic concepts  that  are  formal  with  issues  of  culture.  Etnomathematics  connects cultures with mathematics learning. The purpose of this research is to obtain the description of the value of the impostor?s value and growing up to the cultural society of  Waibalun. This type of  research  is a  qualitative research  with  the Etnographic  design.  Data  collection  by  observation,  interviews  and documentation. The subject in this study is three person taken Purposive against public figures who learn and understand well about indigenous homes. The object of this  research is the Waibalun indigenous home. The results of data analysis show that a) Etnomathematical activity in the process of making Waibalun indigenous   homes,   that   is   measuring,   counting   and   designing;   b)   The mathematical values were found in the Waibalun indigenous home consist of, the angle, rectangle, triangle, trapezium, tube and reflections.

Abstract

This study aims to determine the effect of students' mathematical dispositions on mathematical problem solving abilities of students in class VII of SMP. The type of research used is quantitative. The sample in this study was class VII A, amounting to 30 people who were selected using simple random sampling from 6 existing classes. The type of data in this research is primary data with data collection used using a disposition questionnaire consisting of 28 items and tests consisting of 5 items of description. Testing the hypothesis in this study using a simple regression test. After the data is analyzed the regression equation is obtained as follows: Y = 16,312 + 0.523X. before testing the hypothesis, the data normality test and linearity test were carried out. Based on the data analysis, it was found that the t-test = 3.296 with significance = 0.003 and table = 2.048. then t count = 3.296> 2.048 = t table means that data is normally distributed. To see the achievement of the disposition indicators of junior high school students in the junior high school class, the average of each indicator is calculated and the achievement of the mathematical disposition indicator is 50.08%. Whereas for grouping mathematical dispositions, problem solving abilities obtained the highest dispositions having an average of 63.04, moderate dispositions having an average of 43.56, and low dispositions having an average of 40.51. Thus, it can be concluded that there is an influence of mathematical disposition on mathematical problem solving abilities of students of junior high school class.

Abstract

The research aims to get an overview about the ability of students in solving mathematical problem based on their emotional intelligence. This is qualitative research with a case study design. The subjects of this research were seventh-grade students who has high emotional intelligence, consisting of a student from catholik junior high school in Kefamenanu and one students from state secondary school in Kota Kupang, They were obtained using purposive. The data were collected using a questionnaire of emotional intelligence, a mathematical problem-solving task, and a interview sheet. The analysis of what is obtained from both subjects, being the high crossing of catholik junior high school students Kefamenanu, it is obtained from cross-leg?s ability: students can understand the matter, make quick plans, to implement completion plans and examine back. The state junior high school in Kupang have the ability of low-vang problems acquired from abilities of emerging problems: students cannot understand matter, students are less able to create completion plans and students cannot examine the return settlement sequences

Abstract

This study aims to determine the effect of self-efficacy and teacher social support on mathematics learning achievement of class VII students of one of the Private SMP in Kupang city social arithmetic material. The type of research used is quantitative with the statistical analysis used in this study, namely multiple regression analysis. The sample in this study is class VII A, amounting to 25 people randomly selected from 4 existing classes. The type of data in this research is primary data with data collection used, namely questionnaires and achievement test questions. Technical data analysis in this study used multiple regression analysis. Based on the partial test results on self efficacy showed that  = 3.164> 1.71 = , teacher social support obtained  = 2.954> 1.71 = , then with a significant level of 5% there is a partial effect on self-efficacy and social support teacher. Furthermore, the simultaneous test shows that = 55,176 and at a significant level of 5% which means that  = 55,176 > 3,44 = , then there is a simultaneous influence on teacher self-efficacy and social support . So, it was found that self-efficacy and social support of teachers had a significant influence on mathematics learning achievement both partially and simultaneously. Thus, it was concluded that there was an effect of teacher self-efficacy and social support on students' mathematics learning achievement. The coefficient of determination (R Square) = 0.834. This means that 83.40% of the variation in mathematics learning achievement can be explained by variations in the two variables, namely self-efficacy and teacher social support. Meanwhile, 16.60% is influenced by other variables.

Abstract

Penelitian ini merupakan penelitian kuantitatif deskriptif yang mendeskripsikan kemampuan matematis mahasiswa prodi pendidikan matematika FKIP UHN dalam menyelesaikan soal matematika sekolah setingkat SMP dan SMA. Subjek penelitian terdiri dari mahasiswa prodi pendidikan matematia FKIP yang diwakili oleh satu grup untuk setiap angkatan, dengan total sampel sebanyak 76 orang mahasiswa yang mengerjakan soal setingkat SMP dan 76 orang mahasiswa yang mengerjakan soal setingkat SMA.. Hasil penelitian menunjukkan bahwa (1) kemampuan mahasiswa prodi pendidikan matematika FKIP UHN dalam menyelesaikan soal matematika sekolah setingkat SMP dan SMA masih sangat rendah, (2) skor maksimal yang diperoleh mahasiswa dalam mengerjakan soal matematika sekolah masih belum cukup memuaskan, sedangkan skor minimal yang diperoleh mahasiswa menunjukkan bahwa mahasiswa masih belum menguasai matematika sekolah, dan (3) mayoritas mahasiwa masih memiliki kemampuan yang berada di bawah skor 50 dari skor maksimal 100. Ketidakmampuan mahasiswa menyelesaikan soal matematika sekolah merupakan gambaran ketidakmampuan mahasiswa dalam menguasai materi matematika sekolah.
